Both the LTC2941 and LTC2943 measure battery capacity.
The LTC2943 is compatible with the LTC2941, it adds voltage and
temperature monitoring, and uses a slightly different conversion
formula for the charge counter.
To avoid confusion with e.g. the LTC2945, the driver is called
LTC2941 instead of LTC294X.

Add a reset driver for Renesas R-Mobile and SH-Mobile SoCs. It registers
a restart handler to trigger a soft power-on reset through the R-Mobile
System Controller.
The priority of this restart handler is 192, to allow a watchdog driver
to use priority 128.
Note that we do not use syscon-reboot, as the HPB (Peripheral Bus
Bridge) semaphore should be acquired on systems where both the ARM and
SH core are in use. The driver can be extended later to support this,
when needed.

Currently the ltc2952 supports only one button sequence to initiate
powerdown. This is not always desirable, as even prolonged button
presses can happen in use.
Allow ltc2952 users to pick their own power down sequence, by making the
trigger input optional. Since this still means that the ltc2952 may
power down the platform if the power button is pressed for about 5
seconds, we still need to make sure to start the watchdog toggle to
prolong the system power for as long as we need it.
This will still allow the system to control power using the kill signal.

In ltc2952_poweroff_handler it is theoretically possible that the timer
fails to start on first pass (button press), but succeeds in starting on
the second (button release). This will cause the button press to be
misinterpreted, and will incorrectly shut down the system. Because a
picture says more than a thousand words:
Expected behavior:
tmr: ++++++++++
btn: -----__________-----
Faulty behavior:
tmr: +++++
btn: -----__________-----
Legend:
+ timer runs
_ button pressed
- button depressed
To prevent this from happening, check the value of the gpio before
starting the timer. If the button is active, we should start the timer,
else we should stop it.
The situation described can now still occur if the polarity of the input
pin is set incorrectly, but that at least is predictable behavior and
can be detected during the first tests.

After commit b2b49ccbdd (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME within #ifdef blocks depending on
CONFIG_PM may be dropped now.
Do that in drivers/power/pm2301_charger.c.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

On Atmel AT91, the conversion to device tree is now considered complete,
and all machines that were not already converted in 3.18 are assumed to
be unused and dropped by the maintainer.
All remaining board files that were written in C are dropped, and the
ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed
altogether. Cleaning up the last pieces was great fun, so I took the
time to do some of the coding myself and removed several hundred code
lines that ended up unused after the board files were done.
There are still a couple of AT91 specific device drivers that are not
converted to DT (CF, USB-OTG) and currently not working, and the platform
itself is not "multiplatform"-enabled, but both issues are going to be
taken care of in the 3.20 cycle.
This is split out from the other cleanups purely based on the size
of the branch.

Currently, all restart handler use the priority 128, including
watchdogs. Probably most SoC have a watchdog, and some of them
register it also as a restart handler. But if a SoC specifies
a dedicated reboot capability using this syscon driver, this is
usually the preferred reboot method. Hence, raise the priority
of this driver to 192.

This driver register pm_power_off with snvs power off function. If
your boards NOT use PMIC_ON_REQ to turn on/off external pmic, or use
other pin to do, please disable the driver in dts, otherwise, your
pm_power_off maybe overwrote by this driver.
